1)  Modem
   General Information About 56 Kbps Connections
   -In order to achieve 56Kbps connects, there can be only one
    digital to analog conversion between the connecting modems.
    Also, the modems at both ends of the call must support 56K
    connections to achieve 56K speeds. If they are not, they will
    negotiate a standard V.34 rate. Current FCC regulations limit
    download speeds of the modem to 53Kbps.

   -Several factors exist that can limit the modem's performance.
    Factors that can contribute to lower connection rates are:
    * Noisy line conditions on individual calls
    * Dirty or faulty wiring
    * Poor connection ability of the modem/fax machine on the
      other side
    * The Bulletin Board Service, Internet Service Provider or
      On-Line Service Provider may be forwarding the call to
      another location (long distance)to extend their local
      calling areas. To improve your modem performance,
      try connecting to and from different locations.

    Com Port Assignment in Windows 98
    Windows 98 may assign the modem to Com5. Windows applications
    supporting TAPI support the use of Com5. If you have an 
    application which does not support the use of Com5, the Xircom 
    Com Port Select Utility can be used to change the Com port 
    assignment in Windows 98.  It will allow you to select an 
    unassigned com port for use with CBM56WG.  The Com Select 
    Utility is added to the Xircom program group during Utility 
    installation. The Com Port Select Utility is not supported
    under Windows NT. 
    Modem Script Files
    Modem script files for popular applications can be found in 
    the \SCRIPTS directory on the CD-ROM.  See scripts.txt in this
    directory for details on using script files with the CBM56WG.
